The document linked below says:
"The number of questions a pupil answers correctly on each test is referred to as their raw score. Raw scores are then interpreted by comparing them to the performance of other pupils of the same chronological age group by means of so- called ‘normative scores’.
The analysis of raw scores plus the age of the pupils, in the context of large cohorts of pupils, results in a series of ‘normative scores’. Three types of normative score are provided to interpret pupils’ performance on CAT4:
• Standard Age Scores
• National Percentile Rank
Further information about CAT4 scores and their interpretation is given in the section entitled ‘Guidance on scoring and reporting results’ in the Teacher Guidance pack."
So you should have been given more than the score ... ask school for the full information.http://www.gl-assessment.co.uk/sites/gl ... erview.pdf
